To all whom tt may concern:

Be it known that we, JAMES T. KETfiu- LEDGE and RUDOLPH J. PEPPER, citizens of the United States, residing at Sidney, in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in Levels, of which the followingis a specification, reference being bad therein to the accompanying drawings.

This invention relates to certain new and useful improvements in plumb-levels; and it has for its objects to provide an instrument which will be cheap and simple in construction, and in which the working parts will be all inclosed and protected from the weather,

as more fully hereinafter specified. These objects we attain by the means illustrated in the accompanying drawings, in which-- Figure 1 represents a longitudinal vertical 2o sectional view ofonr improved instrument, and Fig. 2 a transverse sectional view thereof.

The letter A indicates the usualbarorframe, of wood, metal, or other material, which is provided with a circular transverse recess extending from side toside, midway between the two ends. Within said recess is located a sheet-metal band or lining, B, which has an opening in the top, as indicated by the letter B. There is also a similar opening through 0 the top, which is closed by a sheet of glass, 0, held in place by means of a metallic plate, D, having an opening, also, in order that the plumb-lever may be viewed from above.

To the opposite sides of the band B are so- 5 cured the frames E, which at their centers are provided with pointed screws F, between which the plumb-lever G is pivoted. The said lever at one end is pointed or formed with an indicator, H, and the lower end is weighted,as indicated.

On opposite sides of the bar A are formed recesses L, for the reception of the metallic rings M, which are for the purpose of contining the glass disks N in place, so as to form a transparentinclosure for the central recess. 5 The disks are provided with graduations P, in the form of a quadrant, upon their faces, so that any angle at which the instrument may be set will be indicated.

Havingthnsdescribedourinveritiomwhatwe 0 claim, and desire to secure by Letters Patent,

In combination with theframe A, provided with a circular transverse recess, the metal band or lining B, provided with an opening at the top, the frames E, secured to opposite edges of said band or lining, the pointed screws F, secured to said frames, the plumb-lever Gr, pivoted between said screws and having a weight and indicator, the graduated glass disks setting in recesses in the bar A,the glass plate 0, setting in a recess in the upper face of the bar over an opening in the lining and in said bar, and the confining-plate D and rings M, the whole arranged substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
